Application `tiled Februar-y1, 1907. Serial No. 355.251.

To all whom it may concern:

Be it known that I, HARRY BECKER, a citizen of the United States, residinfi' at the city of Baltimore,in the county oi Baltimore City and State of Maryland, have invented new and useful Im rovements in Outlet-Boxes, of which the io lowing is a specification.

My invention relates to outlet' boxes for electric wiring, and more particularly to that class of box which is designed for use in place of the porcelain tubeformerly employed.

The object of my invention is to produce a device of the character described of a type similar to what is generally in use,'but having InaWny advantages-thereover.

ith the above and other objects in view,

my invention consists in the construction hereinafter described and shown in the accompanying drawing, in which,

Figure 1 is a side elevation showing my improved outlet'box in use. Fig. 2 is an inverted plan view of the same, a section being taken as indicated by line 2-2 ot Fig. l looking in the direction of the arrow. central vertical section on an enlarged scale of the box itself. l

Referring to the drawings in detail, and particularly to Fig. l, it will be seen that the a pipe 3 of iron or other suitable material which passes through the Wall 4 of a building, and can be rotated about the pipe as an axis to secure desired adjustments.

2 indicates the leads or wires which extend from any suitable insulators or supports arranged 'near the outlet box soA as to take the strain oil of the box as is well known.

As clearly shown in F 3 my improved outlet box consists of a cylindrical casing provided with a neck 5 extending r'roni the side thereof, said cylindrical casing terminating in the upstanding flange 7 'lhc neck 5 is internally screw-threaded as at 6 l'or the 5 purpose of attaching the same to thc pipe 3 as snown in Fig.v l. rThe casing 8 is provided l; with an internally projecting annular flange l 9 lying in a lane at right angles to the sides j of the cylin er, and the upstanding frange 7 j is internally screw threaded as at 14. 'lhe I Fig. 3 is a pendicular to the iace ot the u'all.

casing 8 is preferably formed of cast-iron'or other strong and wear resisting material.

Resting against the ilange 9 is a bushing 10 provided with a collar 11 around its inner edge, and surrounding the-bushing l0 is a sleeve or ring 1 3, the inner end of'which takes against thecollar 1li. The outer edge of said ring is preferably roughened or corrugated as at 15 to provide a hand-hold. 'l' he meinbers 1G and i3 are formed of an. insulating material such as porcelain, hard rubber or other suitable substance, and the bushing 10 is provided in its face with holes 12 for the reception oi the wires 2. The ring 13 may in some instances advantageously be constructed oi metal.

it will be seen that in assembling the parts and then the ring 13 is screwed down over the same and securely holds it in place, while at the same time permitting it to turn or swivel freely. T he object of this construction is clearly shown in Fig. 2. Where the wires extend as shown in full lines, the holes l2 will occupy the position shown, but Where the wires approach the outlet box from some other direction shown in dotted lines at 2', the bushing 10 may readily be turned and adjusted so as to bring the holes l2 into such position will adapt them to hold the wires properly spaced. l regard this 'feature oi adjustability as one of the chiot' advantages oi' my invention, as hiretolore it has been necessary to employ two dill'crent styles of outlet boxes according to Whether thc wires extend approximately parallel with or perlllith the present construction, il. is obvious that Wires approaching from any angle whatever can be' readily accommodated.

A further advantage of my construction resides in the fact that no screws or other fastening devices Whatever are employed,

thereby rreatl f addin(r to the convenience l Having thus described my invention, vvhat Q erf/asse,

I claim as new and desire to secure by Lettersl rated bushino, and a, screw threaded rngsurl0 Patent, is: l rounding sac bushing and Within which said y1.
